Thank you for your valuable feedback. We appreciate you bringing this to our attention. We want to assure you that this is not an issue with the phone, so there’s no need to worry. You can continue to use your device with full confidence.
Your phone can run low on memory when opening multiple APPs continuously. To ensure that your device runs smoothly and efficiently, we recommend periodically closing or cleaning up apps that are not in use, especially those running in the background. This will free up memory and help maintain optimal performance. Additionally, we suggest updating your phone to the latest OTA version.
